The relative permittivity epsilon r of the medium is 2.4 -2.4 3 -3 1.5 -1.5 zero

Question

The relative permittivity epsilon r of the medium is 2.4 -2.4 3 -3 1.5 -1.5 zero All of the above is correct. None of the above is correct. If epsilon r is equal to 1.67, then the intrinsic impedance (in Ohm) is 120 pi -120 pi 314.31 451.9 292.24 -292.24 Zero All of the above is correct. None of the above is correct. A plane wave traveling in medium 1 with epsilon_r1 = 2.25 is normally incident upon medium 2 with epsilon_r2 = 4. Both media are made of nonmagnetic, non-conducting materials. If the electric field of the incident wave is given by E^I = y 8 cos (6 pi times 10^9 t - 30 pi, x) (V/m) Answer the following 3 questions: The value of the voltage transmission coefficient is 8 6e^12.80 1.14 0.86 e^12.80 0.14 -0.14 Zero All of the above is correct. None of the above is correct.

Explanation / Answer

13)

The relative permittivity of a medium is always greater than or equal to 1.

Therefore, the correct options are (a), (c), and (e).
